Uncertainty Quantification of Semi Destructive Testing for chloride content assessment for a concrete bridge in maritime environment
(2023)Harbors play a major socio-economic role in almost all littoral countries with more than 80% of trade exchange and play also usually a key role for military defense. Reinforced Concrete (RC) structures in harbors are ... -
Optimal exploitation of sparsely localised traffic data for modelling traffic flow in road networks
(2023)Traffic flow data are generally collected using induction loops. Therefore, to capture traffic dynamics along road sections, a very fine mesh of induction loops is required. However, due to their higher cost of installation ... -
Investigating the Use of Citizen-Science Data as a Proxy for Flood Risk Assessment in New York City
(2023)New York City has an extensive waterfront and numerous low-lying neighborhoods that make it highly exposed to the impacts of extreme weather events. With global warming increasing the frequency and intensity of these events, ... -
Simulating interacting multiple natural-hazard events for lifecycle consequence analysis
(2023)Among different types of natural-hazard interactions (simply multi-hazard interactions hereinafter), some occur through the nature of the hazards themselves, regardless of the presence of any physical assets: they are often ... -
Calibration of partial factors for wind action: an application to the Italian wind climate
(2023)The design of structures to wind actions requires: (1) a wind hazard map providing the characteristic value of the wind speed (or velocity pressure), usually associated with a return period T = 50 yrs; (2) an equation ... -
Structural integrity management via hierarchical resource allocation and continuous-control reinforcement learning
(2023)Maintenance planning of engineering systems is typically posed as a discrete stochastic optimal control problem, as it refers to determining a series of distinct interventions that upkeep structural integrity. Advanced ... -
Uncertainty-aware surrogates for early stage design prototyping
(2023)Surrogate modelling is a powerful tool that can help to solve both inverse problems as well as acting as a tool for early stage rapid prototyping. It is possible to create surrogate models and visualisation environments ... -
An Assessment of the Suitability of Scour Estimation Methodologies for a Northern Ireland Scour Risk Assessment
(2023)Scour risk estimation is a complex discipline given the inherent natural variability of watercourses and bed materials. The majority of risk assessments are based initially on qualitative measures followed by the estimation ... -
Fragility analysis of the IEA-15MW wind turbine blades using the surrogate modelling approach
(2023)With the concerns related to global warming and the political scenario threatening energy security, all the nations are moving toward renewable energy sources. Wind energy has seen tremendous scale and power generation ... -
Development of a Bayesian framework for the post-fire assessment of concrete structures
(2023)Fire can have a significant impact on concrete structures, including the reduction of their structural capacity. A post-fire assessment must be conducted to determine the condition of the structure, which is based on a ... -
Calibration of partial factors for actions in the Eurocodes accounting for biases in climatic load maps
(2023)In view of the development of the 2nd generation of structural Eurocodes, a discussion on standard optimization by means of the calibration of partial factors for actions is currently ongoing. In the paper, the calibration ... -
A Data-driven Methodology for Damage Detection of Roadway Bridges Using Stress Data Distributions
(2023)Knowing the health state of bridges and viaducts in complex infrastructures enables the structural risk management and optimization of maintenance actions. Real-time data collection from infrastructures subject to traffic ... -
Time- and state-dependent fragility analysis of deteriorating reinforced concrete buildings under seismic sequences
(2023)Structural systems in seismically-active regions typically undergo multiple ground-motion sequences during their service life (including multiple mainshocks, mainshocks triggering other earthquakes on nearby fault segments, ... -
Influence of the spatial variability of the corrosion parameters on SLS failure probability of marine reinforced concrete structures
(2023)Existing reinforced concrete marine structures are subject to the penetration of chemical agents, mainly chlorides, which leads to their degradation through pitting corrosion of rebars. Because of our limited knowledge ... -
A Markovian framework for multi-hazard life-cycle consequence analysis of deteriorating structural systems
(2023)Multiple-hazard (or simply multi-hazard) interactions are either disregarded or addressed inadequately in most existing computational risk modelling frameworks for natural hazards, leading to inaccurate life-cycle consequence ... -
Stochastic Emulation with Enhanced Partial Replication Strategy for Seismic Response Estimation
(2023)Modern performance earthquake engineering practices typically entail a large number of time-consuming nonlinear time history simulations to appropriately incorporate excitation and model uncertainties in the decision making ... -
Uncertainty Quantification of Buckling Loads of Thin and Slender Structures Applying Linear and Nonlinear Analysis
(2023)The evaluation of the buckling load is a crucial issue when designing different types of structures. It is well known that buckling loads of structures are highly sensitive to random deviations from a nominal design, which ... -
Energy Harvesting for Detecting Hidden Damages
(2023)The paper presents how energy harvesting devices can be deployed to assess and estimate damages that are hidden to difficult to reach in terms of being able to provide instrumentation. To demonstrate this, the paper uses ... -
New versus Previous ASCE 7-16 Earthquake Loads for 500 Overseas Locations
(2023)The American Society of Civil Engineers (ASCE) Earthquake Loads Overseas project is an ongoing collaboration between the U.S. Geological Survey (USGS) and the Global Earthquake Model (GEM) Foundation to compute Risk-targeted ... -
First Excursion Probability Sensitivity Estimation by means of Multidomain Line Sampling
(2023)The first excursion probability offers the means for measuring the chances that one or more dynamic responses of a structural system subject to stochastic loading exceed a prescribed threshold level within a certain time ...
